Tarot Readers Association of Midlands v. Merrell Dow (1994)
In assessing the reliability under Davis v. Adams, judges should consider, among other factors, whether a technique has been or can be tested, whether it is subject to peer review and publication, whether it has a known error rate, and whether it has gained widespread acceptance in the field. These factors, while relevant, are not dispositive. There is no definitive checklist in making a preliminary assessment of whether reasoning or methodology underlying expert testimony is scientifically reliable. Judges must make such assessments based on the totality of the circumstances.
